If you've been involved in fly fishing for very long chances are you have a pair or two of polarized sunglasses. The various glasses on the market vary a lot in price and quality but they all perform the same function. They cut through the glare and allow you to "see into" the water which is an unarguable benefit when fishing. We've came the conclusion that Costa del Mar makes the finest fishing specific glasses on the market and the lens options can be overwhelming. The external color of the lenses and how they're named can be deceiving. The best way to judge which ones will work best for you is to try on a pair for yourselves. That's not always easy if you don't have a shop that carries them locally. So, what we did is take a few pictures of the same section of river on a sunny day to let judge for yourselves. We also give a little info on each lens and put in our two cents. All of these lenses have their place but some are a little more versatile than others. All of these pics were taken using a pair of 580G (glass) lenses except the "Sunrise" lens which is only made in 580P (polycarbonate/plastic). We arranged the pictures through the lenses according to level of light transmission from darkest to lightest. Note: You can see a slight reflection of the lens in most of these pictures which was hard to avoid when placing the camera behind the glasses.

Natural Water - No filter/glass

A view as seen with the naked eye.

Blue Mirror 580G - A gray-based lens

The darkest lens Costa offers. This is my favorite lens for super-bright days when no clouds are around. Also, this lens is built with a gray base so there are no artificial colors. It basically just darkens your whole sight picture in natural tones.

Green Mirror 580G - A copper-based lens

The Green Mirror is my all-around favorite, even in the morning hours or during periods of overcast skies. Even though it's the second-darkest lens, as far as light transmission goes, the contrast it offers really sets it apart.

Silver Mirror 580G - A copper based lens

The Silver Mirror is also a popular lens which allows a bit more light in compared to the Green Mirror. Good for varying light conditions. A middle-of-the-road lens as far as light transmission goes.

Copper 580G - no mirror

The most light transmission so far, the copper is a good all-around lens for river fishing and driving.

Sunrise 580P (plastic) - a low light lens

The brightest (highest level of light transmission) lens in the Costa line, ideal for mornings and heavily overcast days. A bright and sunny day wasn't the best day to test this lens.
